Particularly even distribution
Up to 75 % lower formwork oil consumption
Optimum concrete surface structure
Low energy consumption
Easy attachment
How it works
To enable concrete parts to be loosened easily from the moulds and to ensure smooth surfaces, release agent must be applied evenly to the moulds. There should be neither too much nor too little formwork oil in the mould in total or on individual spots on the mould. To achieve even distribution at a minimum application rate of the release agent, the formwork oil must be split into many droplets of the same size.
With the BL industrial atomiser from Mantis, it is possible to generate approx. 30 million droplets from 1 ml of liquid. The rotary atomiser works without pressure, and the spray pattern is created by means of centrifugal force and using a specially developed atomiser disc. The droplets are deposited evenly on the surface of the mould by means of the vertical air stream generated by the rotation disc and gravity.
Deployment applications
The BL industrial atomisers can generally be used to apply any liquid. In the concrete industry, particularly in the production of prefabricated concrete parts, release agents such as Betopro® (Ecoratio B.V.), Pieri® Decobio S (Pieri GmbH) or Rheofinish® (BASF Construction Polymers GmbH) are applied using these atomisers.
There are two main areas of application:
Large-scale application, e.g. on long manufacturing lines for large prefabricated concrete parts such as concrete element ceilings and walls
Flat moulds for prefabricated concrete parts, which are manufactured using the wet-cast process where optimum surface quality on the visible side is critical.
The modular design enables this technology to be integrated into virtually any process chain.
Advantages
Extremely even oil application and therefore optimum concrete surface quality
Virtually no mist thanks to uniform droplet size and minimal pressure
Release agent consumption reduced by up to 75%
The BL industrial atomisers can be integrated into existing systems in various ways:
Fitted above a transport unit which moves the moulds under the atomiser.
Fitted to a portal, which moves the atomiser over the moulds.
Mounted on a mobile frame, which is pushed over the moulds to be sprayed.
Metering and feeding the formwork oil to the atomiser requires pumps that work at maximum 1 bar of pressure. Alternatively, flow meters/metering valves can be used for metering if the formwork oil tank is located above the atomiser and gravity then transfers the release agent to the atomiser. Mantis offers a complete pump unit, which has already been specially adapted to the industrial atomisers, ensuring optimum atomiser functionality.
An electronic controller for the BL industrial atomisers and the pump unit is also available from Mantis.
Alternatively, the atomisers and the pump unit can be operated via the production line controller if the plant manufacturer offers the appropriate software and interface.
